Abstract(in English) | A technological challenge of LTE(Long Term Evolution) class RFIC is to solve desensitization of receiver circuit caused by the harmonics of clock signal of RF-digital circuits implemented in the in the same IC chip. This problem turns out to be noticeable as the degital assist technique for Si-CMOS circuit becomes popular. This paper explains a new technology to suppress electric current-driven noise on IC chip by utilizing ferromagnetic resonance losses of magnetic thin film in a popular LTE downlink frequency band of 2GHz range. The in-band spurius level was suppressed by 10dB while keeping the Throughput fraction higher than 95%. |
